Activity after ICD implantation may predict survival

Researchers found that patients with higher activity levels after ICD implantation had a 40% lower risk of death at four years compared to those with lower activity. The study analyzed over 98,000 patients and showed that even small increases in activity were associated with a significant reduction in mortality.

Office bacteria all around us, especially in men's offices

A study published in PLOS ONE found that office bacteria are most abundant on chairs, phones, and human skin, with over 500 bacterial genera identified. The study also revealed that men's offices have significantly more bacteria than women's, but the diversity of communities didn't show significant differences.
